1、 Due to the different printed materials carried by printing machines, one is printed on tinplate and the other is printed on cardboard, the auxiliary machines of tinplate printing machines are much more complex than those of cardboard printing machines, so the price of printing equipment is much higher.

2、 Because the material of tinplate is insoluble in water, unlike paper, it can adsorb solvents. Therefore, after printing ink, tinplate needs to be baked in a high-temperature oven to dry the ink. Therefore, a complete tinplate automatic printing line usually has a total length of about 50 meters, with precise equipment and a large volume.

In the end, due to the high hardness of the raw material for tinplate boxes, continuous output equipment such as Xian input cannot be used in the printing process like cardboard. Therefore, the cost of equipment for pushing, aligning, and stacking is much higher than that of cardboard printing machines.
